To all 'whom t may concern:

Beit known that I, HENRY HEss, a citizen of the United States, residing at Wawa, 'in the county of Delaware and State of Penn- 5 sylvania, have invented certain-new and uselful Improvements in Antifriction-Bearings,

of which the following is a specification, reference being had therein to the accompanying drawing. n My invention relates to anti-friction beari ings, and Inore particularly to that class thereof designed to resist both radial and` end thrust.

Generally speaking, it comprises three sets' most compact and ellicient form, I connect them in such way that one of the casing members of each of the radial bearings forms a part of or is connected to one of the elements of the thrust bearing, and ordinarily so that the inner casing member of the outer radial bearing and the outer casing member of the inner radial bearing thus form a part attached I have shown several preferred forms lof this construction, but obviously many changes and variations may be made therein without departing from the spirit of the invention, and I desire it to be understood that it is not limited to any specific form or. arrangement of parts, except in so far as such limitations are specified in the 45. claims.

Referring to the drawings: Figure 1 is a transverse sectional view of an antiefriction bearing, having my invention applied thercto; Fig. 2 is a plan view of the same,7with certain portions removed to show the relation of the operative parts; Fig. 3 is a transverse sectional view of a bearing illustrating another form of my invention; and

Fig. 4 is a similar sectional view illustrating still another form. 2

of or are connected to the selected element of the thrust bearing. In the drawings hereto Referring first to Figs.l 1 and 2 of the drawings, the thrust bearing comprises the bearing plates or casing members A and B -formed respectively with tracks or ways a, b, wherein are interposed the rollin elements or balls-C, in the manner well un erstood in the art. The balls C are spaced and held in position bythe cage M, the construction and arangement of which are shown more clearly in Fig. 2, but. which may be of any desired shape or construction. The casing members or bearingplates A, B, of the thrust bearing are connected to the operative parts, so as to sustain end thrusts. In the present instance, the two radialbearings, between which the thrust bearin is located, are connected to or integral with the cage M, this general arrangement being peculiarly adapted to provide a combined bearing, which is not only simple and cheap in point of manufacture, but also extremely compactand capable of the practical requirements for which it is intended. Around the thrust bearing previously described is located the,

outer annular bearing, which comprises the outer casing element or ring G and the inl ner casingelement orring I, formed respectively with the tracks or ways g and i,

wherein are located the rolling elements or balls I-I, in the manner well understood in the art. Inside'of the thrust bearing is located the inner radial bearing, which comprises the outer casing member or ring D and the inner casing member or ring-F, formed respectively with the -tracks or ways al and f, wherein are located the rolling elements or balls-E. The inner easing member I of the outer radial bearing and the outer casing member D of the inner radial bearing, as previously stated, are connected to or integral with the cage-` M, which con- -stitutes one of the elements of the thrust bearing. When the cage M is constructedk of proper material, having the requisite strength andy durability, the casing members or rings I and D may be formed integrally therewith, but if otherwise, they are formed independently and then connected to the cage in any desired or suitable manner. The two radial bearings referred to may be assembled in any well-known way, although I prefer to construct them .with tracks or ways of the uninterrupted type, which are assembled by eccentric displacement according to the Conrad method. However, the

method of assemblage is immaterial and constitutes no part of my inventlon. Thus, instead of employing the Conrad method, 1 n the case' of a full type bearlng, such as 1s illustrated inr Fi 2, the rolllng elements.

may be introduce in any desired manner, as for instance by the well-known filling opening, not shown. The thrust bearing is subsequently assembled by placlng the balls C in their proper recesses m" the cage M and locating the parts between the bearing platesor casing members A and B in the C1 and C2, with an interior or interposedl bearing plate or casing member L and two exterior rings or casing-members A1 and B1,

the 'respective casing members L, A1 and B1 being formed with tracks or ways to receive and retain the balls C1 and C2, in the customary manner and as clearly shown in the drawing. Another distinction over the form previously described is that the tracks or ways for the balls of the two radial bearings are formed in part in a different element of the thrust bearing, to wit, the interior bearmg plate or casing member L, instead of in the ball cage M, as shown in Figs. 1 and 2. The outer lradial bearing thus comprises balls H1, which track respectively in the outer caslng member G1 and the thrust bearing casing member L, andthe inner radial bearing comprises balls E1, which track respectively in the inner casing member F1 and the casing member L of the thrust bearing. It will therefore be seen that in this particular form the interior. bearing plate or casing member of the thrustbearing also constitutes the inner casing member of the outer radial bearing and the outer casing member of the inner radial bearing. This f combined bearing may also be assembled in any desired manner, as for instance, by ec-4 centric displacement according to the Conrad method. The bearing thus described isV preferably mountedin a casing consisting of two parts J and K, arranged in close relation to the rings 'or `casing members F1 and G1 of the radial bearings', in order to support radial load, and in close proximity to the. casing members A1 and B1 ofI the .thrust bearing, but with sufficient play to permit thrust to be sustained in either direction, all in the manner well understood in the art. i

InFig. 4, Ihave illustrated still another 'form of my invention as applied to a bearing of substantially the type shown in my' application for Letters Patent, No.l 393,322,1-

the outer radial bearing vcomprises the inner casing member I2 and the outer casin member G2, with the balls H2 interposed herebetween. It will be noted that the casing members. D2v and I2,r respectively, are in- 1 tegral with each other and are located in `close proximity to the contiguous parts, and

with only suflicient clearance to permit the formation of oil ilms therebetween. In this form the thrust bearing comprises two sets ofballsC11 and C4, which are interposed respectively between the casing members G2 and D2, and the casing members I2 and F2. As inthe form illustrated in Fig. 3, and due to the integral connection of the casing members I2 and D1, it will be seen that bothy sets of radial balls as well as both sets of thrust balls track partly in the single or' integral bearing plate or casing member I2, D2, the chief distinction being that the two radial bearings are here arranged in parallel planes, instead of in the same plane.

I have thus yshown my inventionv as applied in several diferent forms, in all of which one of the casingmembers of each of the radial bearings forms a part of one of the elements of the thrust bearing. Evi-- dently many variations will suggest themselves to those skilled in the art, and I do lnot limit myself to the exact embodiments of the invention shown, which I have illus trated only in preferred forms, as manyequivalents are equally comprised within its scope.

Having thus described my invention, its construction' and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:
